2. Next, take your knife and cut through the stem, starting at the highest part of the cut. Be sure to make a clean cut right through the centre of the stem.

3. Use your knife to cut down to the lower mark you made earlier. Make sure your cut is as straight as possible. Once you reach the bottom of your cut, keep the knife stuck in the stem and use a pencil/chopstick/skewer to pry open the cut, then pull out your knife.

WHEN IS THE BEST TIME FOR STEM SPLITTING?

Stem splitting is a very aggressive grow technique that’s generating a lot of discussion in the cannabis cultivation community. Those in favour of this technique argue that it stresses the plant in a beneficial way, forcing it to take up more nutrients and produce bigger, more potent buds. Could this be true?

To split the stems of your cannabis plant, you’ll need:

Taking a knife to your cannabis plants a few days before harvest seems pretty counterintuitive. However, many growers say stem splitting can produce bigger yields and more trichomes for tastier, more potent bud. Read on to learn more.

If you are going to experiment with the splitting technique, timing is crucial. Splitting the main stem of a flowering female cannabis plant 7-10 days before harvest is the window that most growers favour.
